Inserts are available in sizes from 2 diameter to 4 1/2 diameter in 2 or 3 disk configuration. The size is based on the outside (OD) diameter of the pipe the Inserts are to fit into. Each application will be different. Some race applications have proven satisfactory with only a single disk insert. The use of CC Inserts allows the user to custom tailor the unit for his specific application. Car Chemistry, Inc. cannot guarantee that any specific application will meet the sound requirements of all municipalities or other governmental agencies. The wide variety of engine configurations and exhaust system designs preclude guaranteeing that all systems using CCInserts will be street legal.

This is a follow up review. I wound up taking the one disk all the way off. Straightened everything else and put the cap with the hole on them. Installed in the header flange. put a gasket on both sides. I am surprised that the car is noticeably quieter. Havnt driven it yet. looking forward to it. Anyway, thanks for a pretty good product. Even though I modified it alot.
